Sample Size Determination for Scientific Studies
Date: 27 May 2026
Time: 9:30am - 4:00pm
Prerequisites: No knowledge of statistical software is required.
Overview: Sample size determination is a central component of planning a scientific study. A well-justified sample size ensures that a study is scientifically credible, ethically defensible, and feasible to conduct.
This one-day course introduces the principles of precision-based and power-based sample size calculations. Using practical examples and simulation-based demonstrations, we will outline the general process underlying sample size determination and show how it can be applied across common study designs. We will also discuss practical challenges that arise in real studies, common sources of uncertainty and complexity, and how to report a sample size calculation in a grant application or study protocol.
